ICE-MAKING APPARATUS.

Application filed March 10, 1921. Serial No. 451,133.

To all whom it may concern:

Be it known that I, OCTAVIUS J. Morons, a citizen of the United States, and a resident of New Orleans, in the parish of 01' leans and State of Louisiana, have invented certain new and useful Improvements in Ice-MakingApparatus, of which the following is a specification.

This invention relates to an ice making apparatus, and more particularly to the stationary ice mold type in which the cakes of ice must be lifted directly from the molds.

An object of this invention is to provide improved means for filling the ice molds by overflowing connections from one mold to another.

Another object of this invention is to provide an improved method of purifying the water, during the process of freezing, by overflowing the impurities through the overflow connections.

Another object of this invention is to provide improved means for lifting the cakes of ice from the molds.

it is also an object of the invention to provide improved means for agitating the water in the molds during the process of freezin";

Other objects relating to details of construction, combination and arrangement of parts will later appear in the description to follow.

The invention is illustrated by way of ex ample in the accompanying drawings, in which: i

Figure 1 is a vertical longitudinal section taken substantially on the lines 2-2' of Figure 1, l

"Figure 2 is a vertical transverse section taken substantially on the lines 33 of Figure 1,

Figure 3 is an enlarged detail view of the combined ice cake lifting and air introducin element provided for each mold.

Tleferring to the drawings more particularly A indicates a steel tank in which the freezing process is carried out. The tank maybe of any shape or length desired.

In the bottom of the tank there is provided floor 10 preferably of wood, as

shown and upon this floor there is spaced in'equal intervals, the cross beams 12 which are also preferably of wood. Each beam has it upper edge protected by a thin sheet metal strip 13. The purpose of the cross beam 12 is to hold the bottoms of the molds V B in spaced relation with one another.

Each mold conforms to the usual shape of an ordinary cake of ice. The molds are placed in rows both longitudinal and transverse of the tank A. A channel or U shaped beam 15 is secured to each side wall adjacent the top thereof, and extending the entire length of the tank; also a cha n el beam 16 is secured lengthwise of the tank at the point where the adjacent ends of molds l3 meet. The molds B are riveted at each of their ends to these channel beams and thus held stationary within the tank A. T he channel beams properly space the molds B from the sides of the tank and also from each other, so that a proper circulation of cooling medium can be made about the molds. 7

An induction pipe 17 is introduced into the tank A near the top thereof for each longitudinally arranged row of molds B. Each pipe 17 is suitably connected through a regulating valve 18 to a water supply pipe 19; also each longitudinally arranged row of the molds B are provided with an eduction pipe 20 which is suitably connected to a drain pipe 21. Only one eduction and one induction pipe are shown by the drawings in Figure 1, however, the water supply pipe 19 and the drain pipe 21 are disposed in parallel relation with the sides of the tank and hence any number of extensions therefrom could be made.

In the bottom or floor 11 of the tank there isprovided a transverse slot or recess 22 in each of which there is positioned a pipe 23. These pipes may be connected in common to a source of steam supply, and serve the purpose of introducing a heating medium about the lower ends ofeach of the molds B when it is desired to slightly thaw the ice about the interior surface of the molds previous to lifting the same from the molds. For the purpose of introducing air into each. of the molds while the water or liquid therein is being frozen, 1 provide a pair of pipes or supporting members 24, the inner ends of which are connected with the T-shaped member 25, as shown, and their outer ends closed as at 26. Each pipe 24k is also provided with a nipple 27 which is threaded into the sides of the pipe and extending at right angles thereto. Into the vertical stem of the T-fitting 25 there extends a pipe
